TECHNICAL FIELD

The present invention relates to a position control apparatus in a TV receiver. More particularly, the present invention relates to a position control apparatus in a TV receiver for moving the TV receiver upward and downward and making the receiver rotary, thereby allowing a viewer to watch a TV in a comfortable state.

BACKGROUND ART

Recently, with a trend of high functions, TV receiver products having special functions rather than simple functions have been developing. In particular, consumers increasingly desire to watch TV in a more comfortable state and to hear more realistic acoustic sound.

Therefore, functions for satisfying the consumers needs have been developed. The television may be classified into a CRT type TV having a Braun-tube and a PDP type TV made of a thin film. In recent years, a PDP TV that has a compact size and is irrespective of a location has been spotlighted as a next-generation TV.

However, a stand type PDP television has to be disposed on a table, etc. like an existing CRT television. Thus, it has a problem that it does not utilize the space properly. For this reason, a wall tapestry type PDP TV has recently been used a lot.

FIG. 1 is a schematic view illustrating the structure for controlling an angle of a TV receiver according to a prior art.

Referring to FIG. 1, the conventional PDP television includes an angular control unit 112 fixed to a wall 1 and having a plurality of fixing grooves 113, a stationary bracket 110 having a fitting groove 114 at its bottom, a rotary bracket 120 having one side attached to a PDP television and the bottom inserted into the fitting groove 114 of the stationary bracket 110, and a link member 130 having one front end hinged to the rotary bracket 120 and the other front end inserted into the angular control unit 112 of the stationary bracket 110.

Therefore, in a state where the stationary bracket 110 is fixed to the wall and the PDP television is attached to the rotary bracket 120, the rotary bracket 120 is inserted into the fitting groove 114 of the stationary bracket 110 and the one front end of the link member 130 connected to the rotary bracket 120 is inserted into the fixing groove 113 of the stationary bracket 110, Thereby, an angle of the PDP television can be controlled from the wall.

In such a television, however, in order to control the angle of the television, a viewer must manipulate the television directly and manually. This makes the viewer troublesome.

Furthermore, as the stationary bracket 110 is firmly fixed to the wall, it is impossible to adjust the height of the television.

BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will now be described in detail in connection with preferred embodiments with reference to the accompanying drawings.

A position control apparatus in a TV receiver allows a viewer to easily control the height and angle of the TV receiver to a viewer's taste.

One example of such a position control apparatus in a TV receiver will now be described in detail with reference to FIG. 2 to FIG. 6. The apparatus includes a frame 10 that is extended along a wall 1 upward and downward, a movable block 20 that is supported to the frame so that it can move along the frame 10 upward and downward, wherein a TV receiver 200 is attached to the movable block 20, and an elevating means 600 for elevating the movable block 20 against the frame 10.

The elevating means 600 (see FIG. 6) includes a screw axis 11 that is supported to the frame 10 so that it is elevated along the frame 10 upward and downward, wherein the movable block 20 is coupled to the screw axis 11, guide rods 12 and 13 supported to the frame 10 in line with the screw axis 11, wherein the movable block 20 is movably coupled to the guide rods 12 and 13, and a driving motor 400 for rotatably driving the screw axis 11.

The driving motor 400 has a decelerator 410 for control the screw axis 11 to rotate at an adequate rate.

In such elevating means 600, the movable block 20 is elevated along the guide rods 12 and 13 and the screw axis 11 according to forward and backward rotary driving of the driving motor 400.

At this time, the driving motor 400 has a proximity sensor (not shown) at upper and lower ends of the frame 10. Thus, if the movable block 20 approaches the upper and lower ends of the frame 10, the proximity sensor is driven to stop operating the driving motor 400. Further, the driving motor 400 is also remotely controlled by the remote controller 310. Accordingly, a viewer 300 can adjust the high and the low of the TV receiver 200 to his or her taste.

Furthermore, the position control apparatus in the TV receiver according to the present invention has an angular control means 350 for controlling the angle of the TV receiver 200 against the movable block 20, as shown in FIG. 4 a. The angular control means 350 includes a rotary central body 30, a vertical protrusion 31 and a link member 32. Meanwhile, FIG. 4 b shows another angular control means 351. The angular control means 351 shown in FIG. 4 b includes a disk type crank axis having a different shape from the rotary central body 30 shown in FIG. 4 a. Therefore, although a rotary motor 500 does not rotate forward and backward, a viewing angle of the TV receiver 200 can be controlled by 360° rotation of the disk type crank axis. FIG. 4 c shows still another angular control means 352. The angular control means 352 has a linear motor that is directly driven in a straight line instead of the rotary motor 500 shown in FIGS. 4 a and 4 b. As the linear motor is used, the viewing angle of the TV receiver 200 can be adjusted even if the rotary central body 30, the vertical protrusion 31 and the link member 32 as shown in FIG. 4 a are not used.

There are shown the angular control means 350, 351 and 352 in FIG. 3, FIG. 4 a to FIG. 4 c, FIG. 5 a and FIG. 5 b. Of them, only the angular control means 350 shown in FIG. 4 a will be below described in order to avoid redundancy.

The TV receiver 200 and the movable block 20 corresponding to it are rotatably coupled by the coupling of reciprocal hinge pieces 21 and 201. The angular control means 350 includes a rotary central body 30 rotated by the rotary motor 500 and having a vertical protrusion 31 at its end, a link member 32 having one end rotatably coupled to the end of the vertical protrusion 31, and a lever member 33 having one end rotatably connected to the other end of the link member 32 and the other end fixed on the TV receiver 200.

As shown in FIG. 5 a and FIG. 5 b, such angular control means 350 rotates around the hinge pieces 201 and 21 by means of a joint action of the rotary central body 30, the link member 32 and the lever member 33 due to forward and backward driving of the rotary motor 500. Likewise, the rotary motor 500 is remotely controlled by the remote controller 310 that has a light-emitting sensor. Accordingly, the viewer 300 can adjust the viewing angle of the TV receiver 200 to one's taste.

Although it has been described that the viewing angle of the TV receiver 200 is adjusted upward and downward, those skilled in the art will appreciate that the viewing angle of the TV receiver 200 can also be adjusted right and left.

By remotely controlling the driving motor 400 and the rotary motor 500 forward and backward using the remote controller 310, it is possible to adjust the height and angle of the TV receiver 200.

FIG. 7 and FIG. 8 show another embodiments of the elevating means. The elevating means 700 and 800 includes a screw axis 11 having guide slot holes 14 and 15 lengthily formed on the frame 10 and supported to the frame 10 rotatably upward and downward, wherein movable blocks 20 a and 20 b are coupled to the screw axis 11, a guide roller 16 rotatably coupled to the movable blocks 20 a and 20 and slidingly coupled to the guide slot holes 14 and 15, and a driving motor 400 for rotatably driving the screw axis 11.

The movable block 20 a is coupled to the screw axis 11 and the movable block 20 b has the TV receiver 200 installed thereon. Furthermore, the driving motor 400 has a decelerator 410 for rotating the screw axis 11 at an adequate rate.

The elevating means 700 and 800 make the elevating operation of the movable block 20 further smooth by means of the guide roller 16 that moves along the guide slot holes 14 and 15.

Furthermore, in the present invention, the angle of the TV receiver 200 can be adjusted against the movable block 20, like in the above embodiment. In this case, as its construction is same as that of the previous embodiment, detailed description on it will be omitted for simplicity. Further, the driving motor 400 and the rotary motor 500 have proximity sensors (not shown) at the upper and lower ends of the frame 10. Thus, if the movable block 20 approaches the upper and lower ends of the frame 10, proximity sensors are driven to stop operating the driving motor 400 and the rotary motor 500. Further, the driving motor 400 and the rotary motor 500 are also remotely controlled by the remote controller 310.

FIG. 9 shows still another embodiment of the elevating means. An elevating means 900 includes first and second rotating bodies 17 and 18 having guide slot holes 14 and 15 lengthily formed in the frame 10, wherein the first and second rotating bodies 17 and 18 are rotatably disposed in the upper and lower ends of the frame 10, respectively, track bodies 19 a and 19 b that revolve on the first and second rotating bodies 17 and 18 in an infinite track and are fixed to the movable block 20, and a driving motor 400 for rotatably driving the first and second rotating bodies 17 and 18 to move the track bodies 19 a and 19 b rotatably upward and downward.

The first and second rotating bodies 17 and 18 may be chain sprockets and the track bodies 19 a and 19 b may be chains. Furthermore, the first and second rotating bodies 17 and 18 may be pulleys and the track bodies 19 a and 19 b may be ropes.

Such elevating means 900 is designed to move along with upward and downward movements of the track bodies 19 a and 19 b by the driving motor 400 and the decelerator 410 since the movable block 20 is fixed to the track bodies 19 a and 19 b being chains or ropes.

Even in this embodiment, the angle of the TV receiver 200 against the movable block 20 can be adjusted. In this case, as such construction is same as the above construction, detailed description on it will be omitted for simplicity. Furthermore, in the driving motor 400 and the rotary motor 500, the proximity sensors (not shown) are disposed in the upper and lower ends of the frame 10. Thus, if the movable block 20 approaches the upper and lower ends of the frame 10, the proximity sensors are driven to stop operating the driving motor 400 and the rotary motor 500. Further, the driving motor 400 and the rotary motor 500 are also remotely controlled by the remote controller 310.

It is to be understood that the position control apparatus in the TV receiver 200 according to the present invention is not limited to the above embodiments, but may be modified in various ways without departing from the scope and spirit of the present invention. For example, it has been described above that the angular control means is designed to rotate the TV receiver by means of a joint action of the rotary motor. However, the movable block may be fixed to a cylinder and the TV receiver may be connected to the end of a cylinder rod, so that the TV receiver can be rotated by the operation of the cylinder.
